Hi all,
It would be useful if I could disable PV inverters individually via VenusOS. This is particularly useful in off grid system when the batteries are (nearly) full and there is not much load. When a sufficiently significant load would appear, the PV inverter(s) can be turned back on, of course with some hysteresis applied. The idea is that the PV inverters are responsible for the bulk of the charging but, as charging via a Multi is a bit "clunky" (not my words, but Victron's :-) ).
It is possible to disable/enable all PV inverters via com.victronenergy.vebus.ttyUSB0/PvInverter/Disable. I assume VenusOS achieves this by telling the Multi to raise the frequency to the value as specified in the PV assistant parameter "The PV inverter will disconnect when the frequency is higher than".
There is also com.victronenergy.settings/Settings/Fronius/Inverters/<serial>/IsActive for each individual PV inverter but as expected this disconnects the PV inverter from VenusOS but doesn't stop it generating power.
Is it possible to turn individual PV inverters on & off via VenusOS using dbus or MQTT?
